Virtual reality (VR) has evolved from a technology of the future into a practical educational tool for students to interact with the world in ways previously not possible. Many K–12 and college courses use free, off-the-shelf VR apps, such as Google Expeditions and Google Earth to explore global landmarks, Lifeliqe to learn about human biology, and Tilt Brush to sketch or paint in three dimensions. Wearing a VR headset immerses the viewer into a world that they might never see in person, or an imaginary world that exists only virtually.
